Customer reviews are one of the most valuable tools we offer customers for making informed purchase decisions, and we work hard to make sure they are doing their job. In just the past year, we’ve improved review ratings by introducing a machine learned algorithm that gives more weight to newer, more helpful reviews; applying stricter criteria to qualify for the Amazon verified purchase badge; and suspending, banning or suing thousands of individuals for attempting to manipulate reviews.

We’re in a golden age of Machine Learning and Artificial Intelligence (AI). As a scientific community, we are still a long way from being able to do things the way humans do things, but we’re solving unbelievably complex problems every day and making incredibly rapid progress.
